A method for detecting physical properties of high-density textiles

Abstract

The invention relates to a method for detecting physical properties of textiles, which comprises sampling three times, selecting at least four weft test pieces and at least four warp test pieces on the same fabric to be sampled each time; The outer edge of the original wire is evenly disassembled, and the width of the test piece is adjusted to 40-60mm; the test is carried out one by one by a tensile testing machine, the test environment is 57% RH, the temperature is 25°C, the pulling speed is 100-150mm / min, the maximum The strength value is 500N, the maximum elongation value is 40-50%, and each test piece is measured with a length of 200-300mm; get rid of abnormal values, and keep the test results of three weft test pieces and three warp test pieces. The invention forms a reasonable and effective detection method, which can objectively detect various tensile test values ​​of the fabric, thereby determining its physical property status, objectively reflecting the breaking ability and tearing ability of the fabric, and is beneficial to improving the product quality of textile production.

Description

technical field [0001] The invention relates to the performance testing technology of textiles, in particular to a method for detecting physical properties of high-density textiles. Background technique [0002] In the production process of products in different fields, how to improve product quality and further reduce the defective rate has always been the goal pursued by every enterprise. High-quality products are also an important manifestation of enterprise competitiveness. Therefore, in the field of textile technology, R&D personnel are also constantly working on the quality of their own textiles, and have produced testing items for textiles. There are many items that must be checked for physical property testing of different textiles. Through the testing of these items, it can be directly judged The quality of textiles is good or bad. [0003] The quality is directly related to whether it can meet the needs of various users. If the performance of the applied textile i...

Problems solved by technology

In addition, the factors that affect the performance of textiles also include the color difference index of the fabric. Different batches of dyed fabrics of the same type will have batch differences. For the quality of fabric products, the color difference between the left and right of the fabric is also not allowed in terms of quality requirements

[0005] Those skilled in the art have analyzed the deficiencies of the existing known technologies. In the past, when the physical properties of textile products were tested, it was not enough to characterize the physical properties of the textile itself, especially when reflecting the fabric breaking ability and tearing ability of the textile. It seems that it is not objective enough. After the testing process is carried out, in fact, many invalid test results are produced. Even if it is completely replaced by automatic equipment, due to the inappropriate sampling method, it still cannot reflect the physical properties of the fabric, which will improve the quality of the product and the quality of the product. Productivity gains, etc., are not beneficial
